LOCK.

SPECIFICATION forming part of Letters Patent No 1 5,390, dated February27, 1 894.

Application filed February 16,1893. Serial No. 462,650. (No model.) i

To all whom it may concern.-

Be it known that I, JonN F. WILLIAMS, a citizen of the United States,residing at the city of Atlantic, in the county of Cass and 5 State ofIowa,have invented certain new and useful Improvements in Locks; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itapro pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in locks and it consists in thepeculiar construction and combination of the parts that will loe morefully set forth hereinafter and particularly pointed out in the claim.

The objects of myinvention are to provide zo a strong, durable, andspringless lock particularly adapted for stables, granaries, coalhousesand other out buildings, and by means of which such buildings can bereadily fastened, or looked.

2 5 thedevice illustratedv in the accompanying drawings in which- Figurel is a perspective view of the lock applied to a building showing thedoor locked. Fig. 2 is a perspective view of the lock ap- 3o plied to abuilding having the door removed. Fig. 3 is a side elevation of theinner side of the lock. Fig. 4 is a top or plan view of the lock havingthe case containing the locking mechanism removed. Fig. 5 is aperspective view of the case containing the locking mechanism. Fig. G isa side elevation of the case containing the locking mechanism having itsouter side plate removed, showing the mechanism within. Fig. 7 is aperspective 4o view of the partition plate having the tumblers pivotedthereto. Fig. 8 is a perspective view of the circular locking bolt. Fig.9 is side elevation of the key. Fig. 10 is a top or plan view of thedoor fastening. Fig.

ll is a perspective view of the sliding bar.

Similar letters refer to similar parts th roughout the several views.

M, represents a portion of the side of a building having hung theretothe door G.

I attain these objects by' I, is a portion of a door casing,and J, isthe 5o door jamb.

H, is a door pull secured to the door.

T, is a metallic plate secured to the door to protect it from the wearof the fastening.

K is a plate secured to the door casing I, 5 5 by means of the screwse4, and having the notch or slit d2, the slots h h', and d d', and thekey Ways m m.

P, is a casing made integral with the plate K, and which projectslaterally therefrom, 6o and incloses a portion of the door fastening A,and consists of the top platefz, the bottorn platefg, of the same shapeas the top plate, the side plate g2, and t-he plate orbridge n4, all ofwhich are made integral.

n2 n2, are flanges which project from the casing P, and are madeintegral therewith, they are secured to the door jamb, by the screws t2t2.

A, is the door fastening having the hook t, 7o and arm a', and theapertures e', and d. It is pivoted to the casing P, by means of thepivot g', which passes through the aperture d.

E, is the case containing the locking mechanism, consisting of thecircular top plate b, the side plates a, and e, and the bottom platef,which is cut away at its ends forming apertures e3 e3, for the passageof the ends of the circular bolt B. The plate a, is provided with theslots t', and n', the threaded 8o apertures s s, and the key Way m2, theplate e, has'the aperture m3, for the reception of the inner end of thekey. i

R, is a lug projecting from the plate g2, and which enters an aperturein the door casing S5 I, adapted to receive it. The case E, is securedto the plate K, by the screws a2 a2, which pass through the plate K, theapertures s s, in plate a, the apertures a3 as, in partition plate D,into plate e.

B, is a circular bolt located between the partition plate D, and thecircular plate b, having its ends constructed round, and of suitablesize to easily enter the aperture b', in the plate f2, and the aperturee', in the fas- 95 teningA. It is provided with the pin n, whichprojects therefrom, and passes through the slots t', and h', and extendsoutward beyond the plate K, and by means of which the bolt can bereadily moved'with the fingers. The bolt is located in such a positionthat, when the door is closed, the end of the bolt next to the fasteningis situated. directly over the aperture Z9', of the plate f2, and theaperture e', in the fastening, so that when that end of the bolt ismoved downward it enters the aperture e', and locks the fastening.

D, is the partition plate centrally located in the caseE, havingpassingsnugly through it the pin e2, one end of which enters the plate a, andthe other end the plate e. The four tumblers L, are pivoted to theopposite sides of the partition plate D, two being pivoted to each endand side of the plate by the pivots a4 a4.

C, is a sliding bar which rests upon the platef, and is provided withthe notches h h, and the rib g, having the notch or ward i, it hasprojecting therefrom the pin m, which passes through the slots n', andd', and eX- tends outward beyond the plate K, and by means of which thebar can be slid with the fingers.

N, is the key used in connection with the lock.

The operation of Iny device is as follows: When the circular bolt is inthe position as shown in Fig. 6, the door if closed can be readilyopened by pushing the hooked end of the fastening from the edge of thedoor with the fingers. If the door is open it can be fastened by simplyclosing it, as the door glides. past the hooked end of the fastening andstrikes the arm a', which forces the hook over the edge of the door andfastens it. Then if it is desired to lock the door it can be done bypushing the pin n, to the end of the slot h', next to the door, whichforces the end ofthe circular bolt next to the door into the aperturee', of the fastening and locks it, and by pushing the pin to the otherend of the slot the bolt is removed from the fastening and unlocks it,but when the end of the bolt is in the aperture e', of the fastening asabove explained, if it is desired to lock the fastening more securely itcan be done by pushing the pin m, to that end of the slot d, thefarthest from the door, which forces the end of the bar C, under thatend of the circular bolt the most remote from the door, and permits thetwo tumblers the farthest from the door to enter the notches h, adaptedto receive them and lock the bar C, with its end under the end of thebolt, which to unlock the key N, is inserted inthe lock and turned halfway around, which movement of the key p disengages the tumblers from thenotches in the bar .and forces the bar from under the end of the bolt B.The notch n3, in the key is made of suitable size to permitthe rib g toenter it when the key is turned in the lock.

The lock is constructed so thatit is reversible, and if it isr desiredto reverse it, the case E, has to be secured tothe other end of theplate K.

I-Iavihg described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The fastening A, pivoted to the door casing or j amb, the circular boltB, supported by a suitable frame and located so that the. end of thebolt can be made to engage with the fastening and lock it, the slidingbar C, resting upon a suitable support and adapted to pass under one endof the circular bolt. when the other end of the bolt isv engaged withthe fastening, and the tumbler L, pivoted above the sliding bar andadapted to enter a. notch in the bar when it is under the end of thebolt whereby the bar is locked, all combined substantially as described.

In testimony whereof I affix my signature iu presence of two witnesses.

JOHN F. WILLIAMS.
